BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 228,434, dated June 8, 1880,

Application filed April 21, 1880. (No model.)

To all whom it may concern Be it known that I, ALBERT ALBERTSON, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Bottle-Stopper, (Case 13,) of

which the following is a specification.

My invention relates to improvements in that class of bottle-stoppers which are placedwithin the neck of the bottle and attached to a stem which projects out of the mouth of the bottle and it consists of a stopper composed of a rubber disk or collar attached to a stem which is passed through a slot in a loose top plate that covers the mouth of the bottle.

The stem has a stop or shoulder, which, when passed through the slot of the top plate and turned aside, will rest on said plate, and thereby hold the stopper in position to completely close the bottle.

In the accompanying drawings, Figure 1 represents a vertical cross-section of a bottle provided with my improved stopper, the section being taken on line 00 m of Fig. 3, and the stopper represented in position to close the bottle. Fig. 2 is a similar view of the bottle and stopper, representing the bottle partly opened. Fig. 3 represents a top view of my improved stopper and the bottle to which it is applied. Fig. at is a side elevation of the same; Fig. 5, a side view, showing the bottle entirely opened. Figs. 6 and 7 are representations of a modified construction of my improved stopper, Fig. 6 showing it closed and Fig. 7 partly opened.

Referring to Figs. 1 to 5 of the drawings, A represents the bottle; B, its neck 5 O, its head, and to its mouth. i

D represents the stopper, which is composed of a rubber collar or disk, I), attached to a stem, E, which is passed through it, the said rubber part I) being secured to the stem between two metal or other stiff plates, (1 e. The upper end of the stem E is bent to form a suitable handle, f, which, by resting on the head 0, prevents the stopper from falling into the bottle, as in Fig. 2. Below the handle f a shoulder, g, is formed on the upper part of the stem E.

F represents a loose cap-plate, which is provided with an oblong slot, h, and adapted to cover the bottle. The upper side of the capplate F is, by preference, formed into a horizontal spiral, j, around the axis of the same. The sloth, it will be observed, is in that part of the cap at which the evolution of thespiral commences.

To close the bottle the stopper is drawn up by means of the handle until it bears against the shoulder at the junction of the hold of the bottle with the neck, the cap-plate F being in position on the head of the bottle with the slot h aligned with the shoulder g of the stem. The latter passes through the cap until the shoulder is above the same, when, by turning the stem axially, the shoulder g is placed at an angle to the slot h, and by engaging the plate in this manner it holds the stopper up against its seat in the bottle. This closes the bottle; but to tighten the stopper in place the stem, on being turned axially, causes the shoulder 9 to ascend on the inclined face j of the cap F, and thereby to draw the stopper upward, so that the rubber portion thereof is pressed tightly against the walls of the neck in the manner shown in Fig. 1.

To unstop the bottle the stem is turned until the shoulder g aligns with the slot h, whereupon the stem slips or is easily pushed down through the slot and the stopper drops from its seat, but is prevented from dropping into the bottle by the handle f resting on the plate F, in the manner shown in Fig. 2.

To pour the liquid from the bottle the plate F is lifted off the bottle, as indicated in Fig. 5. The slot It extends from the center of the cap F toward the circumference, and as the stem E 'is also connected with the center of the stopper, the shoulder 9 will pass through the slot It only in one positionviz., when brought around so as to project from the center in the same direction that the slot 72' does.

The modification illustrated in Figs. 6 and 7 consists in making the cap-plate F flat on its upper side, instead of providing it with the spiral or inclined surface, as in the first-described arrangement, so that when the stem is drawn up and the shoulder passes through the slot h and it is turned it securely holds the stopper against its seat; but the stopper cannot be further tightened, as in the construc- Case 0.

The shoulder g on the stem, instead of be ing flat on its lower edge, may be inclined or spirally formed, in which case the inclined face j on the cap F may also be dispensed with.

I claim- 1. The combination of the internal bottlestopper, 1), and its stem E, having a shoulder, g, and suspension-handlej, with the cap or plate F, provided with an elongated slot, h, all arranged so that the stopper is suspended on the plate F by the shoulder y when closed, and by the handle f when opened, substantially as herein shown and described.

2. The cap F, provided with the spiral or inclined upper face, j, and with the elongated sloth, in combination with the stem E, having shoulder g, suspension-handle]; and stopper D. all arranged so that the stopper is prevented by the handle f and plate F from dropping into the bottle, substantially as specified.

The bottle-stopper constructed of a rubberbody, I), held between 1'|on-elastic plates d 0, and of a stem, E, having a shoulder, g, above the stopper, and a handle, f, above the shoulder, substantially as herein shown and described.

This specification of my invention signed by me this 28th day of February, 1880.

ALBERT ALBERTSON.
